<div class="textblock"><h3>template&lt;typename T&gt;<br/>
struct nih::Histogram&lt; T &gt;</h3>

<p>A small helper class to compute histograms. Usage of this class is supposed to be coupled with <code>Stats&lt;T&gt;</code>. In order to use this class, one would typically loop once over the values to compute basic statistics with a <code>Stats&lt;T&gt;</code> object, and loop over the values once again to create a <code>Histogram&lt;T&gt;</code>. </p>
